Configuration of time sensitive networking

Abstract

Embodiments of the present disclosure relate to methods, devices, apparatuses, and computer readable medium for macro-diversity transmission in a subnetwork. The method comprises: in response to receiving a first header identification associated with a Time Sensitive Communication (TSC) stream, a first device transmits, to a configuration entity of a transport network, a first stream requirement comprising two or more second identifications. Each of the two or more second identifications is associated with a corresponding second device configured for an interface end station in a first protocol plane. The first device receives communication configuration information indicating second header information from the configuration entity. Then, the first device transmits, to a second device operating as a source interface end station, the first header identification and third header information at least indicating the second header information. The second device is associated with a second identification of the two or more second identifications.
